Spatial and temporal assessment of rural-urban land-use gradient effects on water quality and periphyton communities in tributaries of Durham Region, Ontario
(2016-08-01)This study examines the effects of longitudinal and local land-use gradients on water quality and periphyton within four watersheds representing varying rural-urban land-use types and intensities. Although numerous studies ... -
Spatial peripheral interaction techniques for viewing and manipulating off-screen digital content
(2015-08-01)When an information space is larger than the display, it is typical for interfaces to only support interacting with content that is rendered within its viewport. To support interacting with off-screen content, our work ... -
Spatial sound and sound localization on a horizontal surface for use with interactive surface (tabletop) computers
(2012-08-01)Tabletop computers (also known as surface computers, smart tables, and interactive surface computers) have been growing in popularity for the last decade and are poised to make in-roads into the consumer market, opening ... -
Spring Stepper: a makerspace controller for seated hands-free locomotion in virtual reality
(2019-12-01)Natural locomotion is crucial for improving presence in a virtual environment (VE), while also reducing simulator sickness. While research in various areas of virtual reality (VR), such as head-mounted displays (HMD) and ... -
Stability of heroin metabolites and oxycodone in rat hair and liver during decomposition
(2010-01-01)The aim of this study was to investigate the influence of soft tissue decomposition on the stability of drugs incorporated in hair antemortem. Two burial trials were conducted: in the first trial, rats were administered ... -
Stereoscopic depth axis interaction: A study of performance and engagement in stereoscopic 3D games.
(2014-01-01)Game developers strive to maximize immersion and engagement, to emotionally involve the audience in their material. One technique used to increase engagement is the development of new technologies, such as Stereoscopic ... -
StoryPass: a system and study for memorable secure passphrases.
(2014-10-01)The goal of this thesis is to study the implementation of a passphrase system that implements new creation policies, called StoryPass. We are motivated to do this research as current text-based authentication methods, ... -
StoryTIME: development of a tangible interface for storytelling
(2018-08-01)The production of 3D digital animated sequences is an iterative process where ideas are scrutinized by members of the production team until they are finalized. Production teams are comprised of many individuals with varying ... -
Strategies and applications for creating more memorable passwords
(2016-01-01)As we continue to learn and grow in an ever evolving technological age, we deepen our understanding of the importance of authentication. There are many different types of authentication, each exhibiting their own strengths ... -
Structure guided image restoration : a deep learning approach
(2019-05-01)Image restoration aims at recovery of degraded images and estimating the original. Over the past few years, computer vision research has been dominated by deep learning techniques in part due to advances in computing ... -
Study of a 2 dimensional aggregation model with non-linear adaptations
(2018-08-01)In this paper we will explore the impacts on collective animal motion of adding non-linearity to the animals’ turning rate in a 2-dimensional model of aggregation. The model in question was proposed by Fetecau and implements ... -
Subgraph classification through neighborhood pooling
(2023-06-01)Subgraph classification is an emerging field in graph representation learning where the task is to classify a group of nodes (i.e., a subgraph) within a graph. Graph neural networks (GNNs) are the de facto solution for ... -
Supporting student success with machine learning and visual analytics
(2019-08-01)Post secondary institutions have a wealth of student data at their disposal. This data has recently been used to explore a problem that has been prevalent in the education domain for decades. Student retention is a complex ... -
A survey of algebraic algorithms in computerized tomography
(2010-08-01)X-ray computed tomography (CT) is a medical imaging framework. It takes measured projections of X-rays through two-dimensional cross-sections of an object from multiple angles and incorporates algorithms in building a ... -
